It's easy to get involved: no really !

From basket case to:“LibreOffice is now ridiculously easy to build”

Karl Fogel – (now working on “Producing OSS” (v2) …)

Credit to team on gnumake port & other cleanups:

RedHat team are all here today: shake their hands.

We love people to contribute changes:We want your first patch to be non-controversial, and easy, so you're up-to-speed and included outright:http://wiki.documentfoundation.org/Development/Easy_Hacks

Nice, separable, re-usable library: libvisio … thanks to Fridrich Strba & Valek Filippov.

11

Schools: LibreLogo integration ...

A tiny Python implementation

If schools teach 'typing' instead of programming: ensure they have no excuse: add a localised, pretty training language in the office-suite !

Thanks to Laszlo Nemeth

Random Hybrid PDF / Flat ODF demo

Hybrid PDFs are wonderful:Embed the pristine ODF data streams alongside the PDF dataViewable for anyone with or without LibreOffice as createdEditable at full fidelity with LibreOffice

[ of course we import / allow some editing of non-hybrid PDF too ]Flat ODF demo

Save a file – not as .odt but .fodtPretty-printed, easy to generate XML

LibreOffice 4.1 new stuffA small flavour of what we just released …

17

Font embedding for beauty & fidelity ...

Import / export to ODF and OOXML- thanks to Lubos Lunak, Noel Power, Radek Doulik and the Open Source Business Alliance.

Many Base improvements: finally getting some love ...

Also significant work cleaning / debugging base & lots of work on eg. Nanosecond timestamps from many thanks to Lionel Elie Mamane

Limit and Distinct values support: with thanks to Tamás Zolnai

27

Other misc. flavours:

GStreamer 1.0 support (as well as 0.10)~3000 bug fix patches ( 400 from @apache)

cf. ~5000 open bugs @ fdo 10k commits since 4.0Lots of incremental interoperability wins.Ctrl-F search bar: close + match case thanks to Andrzej Hunt & Joren De Cuyper

LibreOffice 4.2 new stuff …the deep, speculative future (6 months out)

29

Lots of great work from GSOC

Windows / VLC integration (if present)Better codec support than windows → use it.

Thanks to Minh NgoFirebird database: move from HSQLDB

Significant speedups, thanks to Andrzej HuntlibCMIS connector for Google Docs

Thanks to Cuong Cao NgoAnd much more ...

ScDocument

Abstraction of Cell Value AccessScBaseCell Usage (After)

Document Iterators

Biggest calc core re-factor in a decade+

Dis-infecting the horrible, long-term, inherited structural problems of Calc.Moving on to real shared formulae & fixed up referencing.Should yield even more memory & performance wins for large sheets.

Lots of new unit tests being created for the first time for the calc core.

A milestone of the code is landed in 4.1Hopefully without significant perf. impact

The major speedups / savings & OpenCL come for 4.2

LibreOffice and GNOME ...

Integration & work with GNOME

Schedule Synchronisationour .2 release matches the 6 monthlyGNOME / distro release cadence.

VCL / Layout integration ...

LibreOffice continues to use it's internal VCL toolkitWith backends for gtk2, gtk3, KDE3, KDE4, TDE, raw X etc.Thanks to Caolán McNamara, Krisztian Pinter, Jack Leigh, Alia Almusaireae (KACST), Katarina 'Bubli' Behrens, Abdulaziz A Alayed (KACST), Jan Holesovsky, Faisal M.

335 dialogs (~50%+) moved to GtkBuilder / glade edited .ui files.Hope to allow (optional) use of native widgets in the future [ gtk+3 ]

LibLibreOffice – prototype:

A tiny static libraryAt run-time, dynamically links / exposes LibreOffice functionality

An abstract & much simplified programming interface:class LibLibreOffice {

    virtual bool initialize (const char *installPath) = 0;

    virtual LODocument *documentLoad (const char *url) = 0;

};

LibLibreOffice *lo_init (const char *install_path);

GNOME / Documents:Currently re-spawns (via a python script 'unoconv') a LibreOffice process to do PDF conversion → evince.Significant setup / tear-down costs → better to link libreoffice ?Ultimately hope to have a tiled document renderer for 'Documents;

libCMIS integration in GNOME

libCMIS – standalone library (thanks to Cedric Bosdonnat)http://sourceforge.net/projects/libcmis/

Uses new “Content Management Interoperability Services” (CMIS) std.http://en.wikipedia.org/wiki/CMIS

Implemented by many servers:MS Sharepoint 2010+. Alfresco + in the cloud, EMC Documentum, IBM doc mgmt. systems, Nuexo, OpenCMS, SAP HANA, etc.

Already have a prototype GVFS backend:http://cgit.freedesktop.org/~cbosdo/gvfs-cbosdo/Help much appreciated to finish & get that into a ship-able state …

libcmis – also talks to Google Docs.

LibreOffice is growing & executingReally improved a lot for developersImproving for users: still a long way to go …

LibreOffice works well with GNOMEWe want to integrate better with all our platforms

LibreOffice has ambitious future plansWe need new hackers to accelerate them ...

Thanks for all of your help and support !we rely on you, to prove the power of Freedom with us.to get people excited about Free Software they use …

Please do get involved and help us ...Oh, that my words were recorded, that they were written on a scroll, that they were inscribed with an iron tool on lead, or engraved in rock for ever! I know that my Redeemer lives, and that in the end he will stand upon the earth. And though this body has been destroyed yet in my flesh I will see God, I myself will see him, with my own eyes - I and not another. How my heart yearns within me. - Job 19: 23-27
